General Safety Information
WARNING
"Maintenance interval depends on the usage and riding circumstances. Clean regularly the chain with
an appropriate chaincleaner. Never use alkali based or acid based solvents such as rust cleaners. If
those solvent be used chain might break and cause serious injury."
• In order to obtain good gear shifting performance, applicable chains have a forward side and a reverse side, and
the sides are marked so that the chains will face the correct way when installed. The proper design performance
will be obtained when the chains are installed so that they face the correct way. If the chains are installed so that
they face the opposite way, they may come off and the bicycle may fall over and serious injury may occur as a
result.
• Use the reinforced connecting pin only for connecting the narrow type of chain.
• If connecting pins other than reinforced connecting pins are
used, or if a reinforced connecting pin or tool which is not
Chain
suitable for the type of chain is used, sufficient connection
force may not be obtained, which could cause the chain to
break or fall off.

change in the number of sprocket teeth, make the cut at
some other place than the place where the chain has been
joined using a reinforced connecting pin. The chain will be damaged if it is cut at a place where it has
been joined with a reinforced connecting pin.
• Be careful not to let the cuffs of your clothes get caught in the chain while riding, otherwise you may
fall off the bicycle.
• Check that the tension of the chain is correct and that the chain is not damaged. If the tension is too
weak or the chain is damaged, the chain should be replaced. If this is not done, the chain may break
and cause serious injury.
• The two left crank arm mounting bolts should be tightened alternately in stages rather than each bolt being fully tightened all at once.
Use a torque wrench to check that the final tightening torques are within the range of 12 - 14 N·m. Furthermore, after riding
approximately 100 km (60 miles), use a torque wrench to re-check the tightening torques. It is also important to periodically check the
tightening torques. If the tightening torques are too weak or if the mounting bolts are not tightened alternately in stages, the left crank
arm may come off and the bicycle may fall over, and serious injury may occur as a result.
• Check that there are no cracks in the crank arms before riding the bicycle. If there are any cracks, the crank arm may break and you
may fall off the bicycle.
• If the inner cover is not installed correctly, the axle may rust and become damaged, and the bicycle may fall over and serious injury may
occur as a result.
• Obtain and read the service instructions carefully prior to installing the parts. Loose, worn or damaged parts may cause the bicycle
to fall over and serious injury may occur as a result. We strongly recommend only using genuine Shimano replacement parts.
• Obtain and read the service instructions carefully prior to installing the parts. If adjustments are not carried out correctly, the chain
may come off and this may cause you to fall off the bicycle which could result in serious injury.
• Read these Technical Service Instructions carefully, and keep them in a safe place for later reference.
CAUTION
• If the chain is on the smallest or intermediate chainring, there is the danger of injury from the tips of the teeth on the largest chainring.
Note
• In addition, if pedaling performance does not feel normal, check this once more.
• Before riding the bicycle, check that there is no play or looseness in the connection. Also, be sure to retighten the crank arms and
pedals at periodic intervals.
• When installing the pedals, apply a small amount of grease to the threads to prevent the pedals from sticking. Use a torque wrench to
securely tighten the pedals. Tightening torque: 35 - 55 N·m {305 - 479 in. lbs.}. The right-hand crank arm has a right-hand thread, and
the left-hand crank arm has a left-hand thread.
• If a squeaking noise is heard coming from the bottom bracket axle and the left crank arm connector, apply grease to the connector and
then tighten it to the specified torque.
• Use a neutral detergent to clean the crank arm and the bottom bracket. Using alkaline or acidic detergents may cause discoloration.
• Do not wash the bottom bracket with high-pressure jets of water.
• If you feel any looseness in the bearings, the bottom bracket should be replaced.
• If gear shifting operations do not feel smooth, wash the derailleur and lubricate all moving parts.
• If the amount of looseness in the links is so great that adjustment is not possible, you should replace the derailleur.
• You should periodically wash the chainrings in a neutral detergent and then lubricate them again. In addition, cleaning the chain with
neutral detergent and lubricating it can be an effective way of extending the useful life of the chainrings and the chain.
• If the chain keeps coming off the chainrings during use, replace the chainrings and the chain.
• When the chain is in the position shown in the illustration, the chain may contact the
front chainrings or front derailleur and generate noise. If the noise is a problem, shift
the chain onto the next-larger rear sprocket or the one after if the chain is in the
position shown in Figure 1. Shift the chain onto the next-smaller sprocket or the one
after if it is in the position shown in Figure 2.
• For frames with suspension, the chain stay angle will vary depending on whether the
bicycle is being ridden or not being ridden. When the bicycle is not being ridden and
the chain is positioned on the largest/larger chainring and on the smallest sprocket, the
chain guide outer plate of the front derailleur may touch the chain.
• The cuffs of your clothing may get dirty from the chain while riding.
• Apply grease to the left and right adapters before installing them.
• For smooth operation, use the specified outer casing and the bottom bracket cable guide.
• This front derailleur is for triple front chainwheel use only. It cannot be used with the double front chainwheel, as
the shifting points do not match.
• When installing the top route type, choose a frame that has three outer casing holders as shown in the illustration
at right.
• Use an outer casing which still has some length to spare even when the handlebars are turned all the way to both
sides. Furthermore, check that the shifting lever does not touch the bicycle frame when the handlebars are turned all the way.
• A special grease is used for the gear shifting cable. Do not use DURA-ACE grease or other types of grease, otherwise they may cause
deterioration in gear shifting performance.
• Grease the inner cable and the inside of the outer casing before use to ensure that they slide properly.
• Operation of the levers related to gear shifting should be made only when the front chainwheel is turning.
• If the brake fluid used in the oil disc brakes is of a type which tends to adhere to the plastic parts of the shifting lever, this may cause
the plastic parts to crack or become discolored. Therefore, you should make sure that the brake fluid does not adhere to these plastic
parts. The mineral oil which is used in SHIMANO disc brakes does not cause cracking or discoloration if it adheres to plastic parts, but
such parts should be cleaned with alcohol beforehand to prevent foreign particles from adhering.
• Do not disassemble the shifting lever unit, as this may damage it or cause mis-operation.
• Be sure to read the service instructions for the Rear Drive System in conjunction with these service instructions (SL-M980-I).
• Parts are not guaranteed against natural wear or deterioration resulting from normal use.
• For maximum performance we highly recommend Shimano lubricants and maintenance products
• For any questions regarding methods of installation, adjustment, maintenance or operation, please contact a professional bicycle dealer.

Gear shifting operation
The INSTANT RELEASE mechanism makes fast releasing possible because cable tension is released immediately when a lever is
depressed.
This release lever is equipped with a 2-way release mechanism which allows release operations to be carried out by either pushing or
pulling the lever.
Both lever (A) and lever (B) always return to the initial position when they are released after shifting.
When operating one of the levers, always be sure to turn the crank arm at the same time.
To shift from a small chainring to a larger chainring
(Lever A)
When lever (A) is pressed once, there is a shift of one step from a
